The rotational period of the moon is blank space question 2 options greater than the revolution period around earth less than the revolution period around earth equal to the revolution period around earth always changing

equal to the revolution period around Earth

Explanation:

The Moon rotates on its axis (lunar rotation) in approximately 28 days and it takes the same time to complete its orbit around the Earth (lunar translation).

In other words:

The moon performs its rotation movement  and translation (around the Earth) in the same time interval.

That is why from the Earth we always see the same face of the Moon, while the other side is always hidden for us.
